Answer: 48.84
Step-by-step explanation:
First, find the perimeter of the rectangle. 12+12+3+3=30ft. Next, find the perimeter of the semicircles. You can tell that if you put the semicircles together it would be a full circle. The formula for the perimeter of a circle is r2pi. The radius times 2 would be 6. Pi is approximately 3.14. 6 times 3.14 is 18.84. 18.84+30=48.84ft. Hope this helped :)

Answer:x=1.5
Step-by-step explanation:
Given
Two points co-ordinates are given
A=(5,-8)
B=(5,4)
let other point be C =(x,y)
Area of triangle is given by
A=20-5y+40-8x+5y-4x
A=60-8x
and A=48 square unit
48=60-8x
x=1.5
As area is independent of y therefore at x=1.5 any value of y will give area of 48 square unit
I can not see the trapezoid
